Today, August 3 at 18:30 Moscow time on the progress in space flight engineer of the International Space Station cosmonaut Sergei Volkov (Roscosmos) has successfully implemented a micro-satellite launch "Cedar". Running is dedicated to the 50th anniversary of the space flight of the first cosmonaut Yuri Gagarin ("Cedar", we recall, was the call sign of the first cosmonaut in the momentous flight.).
Small spacecraft "Cedar" (aka ARISSat-1, it — "Radioskaf-B"), whose mass is 30 kg, set up as an experiment, "RadioSkaf."
The satellite was developed in the framework of UNESCO's education program RSC "Energia" and Kursk State Technical University to celebrate the 50th anniversary of the first flight into space.
Model ARISSat-1 is one of the new satellites, intended for low-cost student experiments and data downlink to Earth on frequencies allocated for amateur radio.
In this case, such an experiment is the atmospheric pressure sensor, created in SWSU (formerly Kursk Technical University). This sensor will collect data on the balance of air at the height of the ISS and the change in concentration with time.
And since the launch of "Cedar" is taking place in the year of the 50th anniversary of Gagarin's launch, aboard satellites placed welcome entries in 15 languages. Apart from them, "Cedar" will broadcast from space Gagarin's historic recording of conversations with mission control. Finally, the student must maintain broadcast satellite with on-board cameras and drop to earth working telemetry.
145.95 MHz — at this frequency to tune the receiver to catch the new satellite signals amateur radio call sign RS1S. This device is shown on the Earth and on the ISS, open and packed. Silver cylinder of the top — one of the most atmospheric sensor Kursk (photos from radioskaf.ru).
Microsatellite "Cedar", prepared for release into free-swimming, can be seen on the video transmitted from the ISS and, in particular, directly from the spacesuits astronauts (frames NASA TV).
"Cedar" delivered to the ISS in late January, the space truck "Progress M-09M".
